Answer: 78.02 cm²
Step-by-step explanation:
1. To solve this problem you need to apply the formula for calculate the area of a rectangle, which is shown below:
[tex]A=l*w[/tex]
Where [tex]A[/tex] is the area of the rectangle, [tex]l[/tex] is its lenght and [tex]w[/tex] is its width.
2. You know that the rectangle has a length of 9.4 cm and a width of 8.3 cm, therefore, you must substitute these values into the formula. Then, you obtain the following result:
[tex]A=(9.4cm)(8.3cm)\\A=78.02cm^{2}[/tex]
